Abstract

We consider diversity for media streaming in a rate-distortion optimizationframework. A sender-driven transmission scenario is investigated, where diversity is achieved by using multiple transmission paths over the network. Theproposed framework enables the sender to decide at every instant which packets, if any, to transmit and over which transmission paths in order to meet arate constraint while minimizing the end-to-end distortion. Experimental results demonstrate the benefit of exploiting packet diversity in rate-distortionoptimized sender-driven streaming of packetized media.
